That is the perfect lift. It's high enough to look modified, and fit oversized tires, yet low enough to not look redneck. It has class. My wife is short and would love being able to jump into that truck without needing a ladder. Dont change a thing IMO...

99-04 has a 5.5" back spacing, and the 05-08 have a 4.5". They sit in an extra inch, they rub on the leaf spring on a hairpin turn. and the inside of the rim rub on the control arm on the 17s, at least they did on my dads 02. hes tried an oem set off of an 05 fx4, i think it had the 18s, and he tried an aftermarket set off an 05 excursion.

theyll fit and you can run em, but theyll rub that there leaf spring.. it sucks..
